Prerequisites

A group list is a great way to manage users in a select team or group on your domain. There is no limit to the number of internal address (addresses within your domain) and a limit of 250 additional members outside of the domain. For example, suppose that you have a billing team you want to group together - bob@domain.com, amy@domain.com, and scott@domain.com. You can create a group list for the team so that they can communicate new upcoming billing updates within the team, at billingupdates@domain.com.
